vitriol against chuck hagel, what is it about? is it for show? is it about something hagel said in the cloakroom? is it the unfairness of vietnam itself, that some went and some didn't? is it about johnson's inability to win that war or end it? what burns so deeply in john mccain these days? it seems to excite those who knew nothing about vietnam but want to replay it. we dig into the deep well of resentment burning in john mccain's patriotic heart. a resentment not against the north vietnamese who imprisoned and tortured him all those years, not against george w. bush and his political henchmen who tried to stain mccain's reputation back in 2000, but against a guy who fought against fear and rallied against wounds just like he did in the same army of america's long nightmare in vietnam, chuck hagel. a nightmare, by the way, whose flashbacks must haunt still the mind and heart of john sidney mccain. i'm joined by david corn and joy reid, both msnbc contributors. both of you, sir and lady, are younger than me, but i'm younger than me, but i'm convinced we're watching a flashback.
